The EG-02 is a standard decay envelope generator.
The decay knob changes the decay phase time from 1 ms to 10 seconds.
Gate signal input to trigger envelope.
Envelope output (0.0 - 1.0 volts).
The EG-02 differs from other envelope generators in that there is no sustain phase. Once the EG-02 receives a gate signal, it instantly ramps up, then decays at the rate determined by the decay knob. This action is regardless of how long the gate signal is held open.
The EG-02 is well suited for percussive and fast burst like sounds.
